CAR-AXLE Box.

SPECIFICATION forming part of Letters Patent No. 247,695, datedSeptember 27, 1881.

Application filed March 3, 1881.

diana, have invented a new and useful Im-' provement in'AxleBoxesaudGovers, of which the following is a specification.

My invention relates to that class of axle- 'boxes for car-trucks whichhave covers sliding in grooves or ways formed on the face of the box;and it has for its object the construction of the box and cover in suchmanner that the cover cannot be removed while the parts of truck are inworking position, and also in such manner that the cover, when closed,will form a tight joint with the face of the box without the use ofsprings or similar means.

In the accompanying drawings, Figure 1 is a sectional view of myimproved axle box and cover, taken on line as w of Fig. 2'; and Fig. 2is a front view of the same.

Similar letters of reference indicate corresponding parts.

A represents the axle-box, and B the cover. The box is formed with itsfrontface, a, slightly inclined toward the body of the truck, and isprovided with the projection catitsupperedge and with the side parallelways or groovesdd. The coveris convex vertically, and formed with loweredge curved under, forming the lip b, and it is provided on its frontface with the projection c for lifting the cover.

The top of the box A is provided with pro- (Model.)

jections, forming the seat a for the arch-bar or equalizingbar of thetruck, and the box is held in place by the pedestal O in the usualmanner.

It will be observed that in order to place the cover in the ways orgrooves in the box or remove it therefrom the cover has to be brought tonearly a horizontal position to cause the lip b to pass the projectionc, and that it must be put in place before the box is secured to thetruck, and also that the cover cannot, therefore, be lost or removedwhile the parts of the truck are in proper position.

It will also be perceived that, owing to the curvature of the cover, awedging effect is produced between the cover and the edges of the waysor grooves, causing the cover to be held firmly against the face of thebox, thus preventing access of dust and all rattling and noise of thecover when the cars are'in motion.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- The combination, with an axle-box having theinclined front face, a, projection c at its upper edge, and grooves d d,of a cover, B, having the lip b on its lower end, as shown anddescribed.
